Endpoint to retrieve workflow status

[reskyner]

Add a view to retrieve workflow status - this should be standardised across however many workflow execution systems we use to: Queueing, running, success, fail

Info needed:

• task id

Workflow code should be written and maintained in a separate repository (e.g. a collection of nextflow, galaxy, squonk etc. workflows) that contains all of the code needed to execute the workflow in/on the correct container/serrvice - the endpoint should return:

When the workflow is complete, a final endpoint will be used to import/download the data
